ABSTRACT:
In an elevator apparatus, a brake device stops a car from running. The brake device can adjust the magnitude of part of a total braking force generated at a time of emergency braking of the car. As an example of the brake device, the brake device has a nonadjustable brake portion for immediately generating a braking force without making an adjustment thereof at the time of emergency braking of the car, and an adjustable brake portion for generating a braking force while making an adjustment thereof at the time of emergency braking of the car.
